Great service. When your salesforce KNOWS product and application both sides WIN.


This is a Dexter OEM brake assembly, so it was manufactured per Dexter spec's and quality control.


High quality, perfect fit, easy installation, I highly recommend these.


Fast, Friendly, Knowledgeable service.


Fit just like described.


We bought bearings,seals,brakes and brake drums for our horse trailer as we travel around with are furry pet.We give a A+ for quality,service and price .will use trailer for all are future needs. Thank you

Jim M.


Just great.We bought wheel bearings,Brake shoes and drum.I just repacked the wheel bearings and everything looks new.Your great company and a good price 2 thumbs up and 2 happy horses.


I removed and reconditioned the axles on my snowmobile trailer. Salt corrosion damaged the brake assemblies. The replacements assemblies from bolted right on and made short work of the brake repair.

Jeff K.


Still working just fine.


Every thing seems to be fine


I bought a new car trailer with brakes on only 1 axle. etrailer had the exact same brakes for me to put on the second axle. These drum brakes were really easy to install, wire and adjust / re-adjust. I'd really recommend brakes on both axles if like me you're towing close to 7000lb. I've made a couple emergency stops around town, and didn't have the feeling i was being pushed by the trailer at all.
I'd also really recommend getting a high tech brake controller if you're buying one. I had a cheap one that really sucked, i had to constantly readjust brake power every time my speed varied (to stop being pushed by the trailer at speed or jerking to a stop at low speed). Annoying and dangerous IMO.


Used these electric brake assemblies to replace the hydraulic units which became useless due to the master cylinder in the coupler becoming rusted and frozen up. Everything about the units was top notch and they bolted directly in place of the hydraulic backing plates. Shipping was fast with detailed follow up provided by Etrailer (probably the best of any internet company I've dealt with.)

Packaging was more than enough with more packing material and staples than was really required. ( 15 staples in the box ends alone where 5 would have been more than enough) Unfortunately, the assemblies were "nested" back to front into one another which caused the brake shoe of one unit to cut off the wire leads of the other. "Back to back" or "front to front" would have solved this issue which has happened to other customers. Additionally, the one plate had dust plugs for the brake adjuster provided while the other one had none. Both of these problems were minor but kept the experience from being totally outstanding.


I ordered a complete brake kit for my 6x10 wells cargo trailer (backing plates wiring, hub assemblies, junction box). The items were not packed well and the brake wire got shredded by the hub assemblies during shipping. A quick call to eTrailer and a replacement cable was sent out right away - great customer service! Installation of this kit was a breeze thanks to the instructional videos available on the eTrailer website. All the items are of excellent quality and everything fit together perfectly. One small wish would be to include the lock washers and nuts (4 per side) that are required to mount the backing plate instead of having to order it a la carte.


Came as described, packaged i a “ bulletproof” package & parts went on without a hassle. Delivery was quick. Only company to trust in trailer maintenence



Perfectly functioning, dead reliable product


Added brakes to my 6X10 Wells Cargo enclosed trailer. They are working great. Easy install. As always, new trailer brakes take some time to wear in before you get full "lock - up" level braking. I'd buy these again. As always, great order and order fulfillment experience with etrailer.


I completely rebuilt my trailer. The brake assemblies ordered were easy to install. It was much easier than trying to rebuild my existing brakes. The instructional videos from made the installation of the breakaway kit a breeze. Shipping was upgraded for free and received my order very quickly. It was a pleasure doing business with


A year ago I ordered 4 trailer brake assembly sets, brake drums and bearings. They arrived quickly and in good condition. Everything fit well and I had no problems when I towed my trailer across the country. I would definitely buy from Etrailer again.


OEM Made in USA and Dexter original. Exact fit. This is the best way to service brake systems especially on tandem axle applications. Great price, great service. Best with new nuts and lock washers and new Dexter drums and did I mention made in USA.


Good product, just what I expected.
be aware that it does not include the nuts for the 4 studs that hold the backing plate to the axle. You'll have to come up with those on your own.

Slim R.


Thank you. No problems.


Great deal! Only cost a few dollars more to replace the backing plate and components than to purchase new shoes. If you're debating whether to replace just the shoes, or the whole backing plate I'd recommend you replace the whole backing plate. It's far easier (4 nuts vs 3 springs and more), and ensures that everything is in good working order. One caveaut, however: it's not easy to replace backing plates when the nuts are severely rusted (in my case, it took cutting most of them off). FYI, I'm using these with drums marked "8-249-07"

NOTE: You'll need (4) 7/16-20 nuts if you're not planning on using the originals. Bolts are included.


10" Electric Trailer Brake Assembly - 23-27 is quick and easy to install. saves hours of frustration trying to assemble brake lining and springs. I recommend to buy the brake drum that goes with the brake assembly also. No power tools needed for this job. View the provided on line instruction and viewing the video was very helpful installing this product. Thank ETrailer


Still got to put them on, but they look good, I forgot to order the brake controller so I missed out on the free shipping,.
Can you make a recommendation for a controller, I have a 2004 Chevy Sub 1500. Nothing fancy

Etrailer Expert

Patrick B.


One of my favorite controllers is the Prodigy P2, part 90885. It has all the important features for a proportional controller, without extra bells and whistles that may be nice but not necessary. A relative new-comer to us, that has been received well so far is the TrailerMate X10, part TM75813. It works well, is pretty inexpensive, but the display is on the bright side and can be harder to read at an angle than the larger LED displays.


Product was as advertised. Form, fit and function were excellant. Assembly was a breeze, especially with the non-polarity of the wires. Just bolt them on, plug them in, adjust them, and go. Recommend buyers also purchase the 4 nuts that hold each backing plate onto the trailer's mounting flange. They do not come with the assemblies, and 7/16 x 20 (fine thread) nuts are getting difficult to come by. I went to my local Lowes to purchase 16 nuts and lock washers for the 4 assemblies I purchased.. They only had 17 nuts in the entire store.


Haven't been able to try them out yet, but they installed pretty easily, even for having never dealt with trailer brakes before. The only complaints I have are that the hardware and adjuster hole plugs were not included. Seriously, can't we add a buck on the price and throw them in?


Perfect replacement if you are experiencing fatigue failures on your brake hardware. Easy installation. 7000 miles since installing and no issues.


About a year ago I replaced all my existing breaks on my camper with these. Swapping them out was painless (first time doing so.) After getting the adjustment correct on the brakes and the brake controller they’ve worked great! We have a lot of hills where we live and camp almost every weekend May-October and have had no issues. I will double check in the spring but as of when we parked for the winter there was no need for adjustment yet, plenty of pad left for another season or two!


Purchased the entire brake and hub assemblies for about the same price as a brake job at the trailer shop. Shipped quickly...etrailer even upgraded my shipping at N/C.

The brake assembly and hubs were simple to install. The brake controller took less than a minute to install.

Good prices, great service. Would definitely do business with etrailer again.

  • How to Pick Out Brake Assemblies for Terry Resort Fleetwood 5th Wheel Trailer
    Picking out brake assemblies for trailer axles is actually pretty easy but I am not able to determine the info I need from your trailer info since it's not something manufacturers keep records of. You do need to order a total quantity of 4 assemblies since To pick out the correct brake assemblies for your trailer you need to know a few things.

  • Troubleshooting Low Voltage Output from Brake Controller
    Something is obviously causing a voltage drop between the brake controller and the trailer connector. The usual culprit in this type of situation is a break in the wire or a corroded wire. Check the wiring under the truck. You should be able to trace the trailer connector wires from the back of the trailer connector up toward the front of the truck. Look for any sections that look like they may have been pinched, frayed or even eaten through. If there are any wires spliced in or quick splices,...

  • How Tight Should the Nuts be When Attaching a Trailer Brake Assembly to a Trailer
    When installing brake assemblies like the Electric Brake Assembly, # 23-27, that you have referenced, there is no specific torque rating when tightening the nuts on the backing plate. Basically you will want them to be as tight as you can get them using the appropriate wrench. You will not need to use a breaker bar for extra torque when tightening the nuts. Take a look at the two videos linked below. Our installer does not mention a specific torque rating, but uses a wrench and tightens...

  • How Do You Know When Trailer Brake Pads/Drums Need to Be Replaced
    You would know to replace brake shoes the same way you would know with a vehicle. If performance is suffering and adjusting the brakes does not help and there are no other issues causing the poor performance it is probably time to change the brake shoes. Some shoes that have pads that are riveted on should be replaced once the pad wears down to that rivet. When you have the hub off the axle inspect the inside of it. Does it look torn up where the magnet rides or where the brake pads touch...

  • Troubleshooting Trailer Brakes that Lock Up w Manual Override of Controller But Not w Brake Pedal
    The fact that the trailer brakes will lock up with the first trailer when you apply the manual override lever indicates that the trailer brakes are probably just fine and that the issue is in the settings of the brake controller. Since I do not know what kind of brake controller you have you might try adjusting the sensitivity of the controller up if it's a proportional controller or the ramp up speed if it's a time delayed. That should allow the brakes to lock up sooner when you apply...

  • How to Replace Manual Adjusting Trailer Brake Assemblies with Self Adjusting Assemblies
    To determine what brake assemblies you would need will require you to measure the inner diameter of the drum hubs as well as the depth like in the picture I attached. I attached a page that has all of our self adjusting brake assemblies for you to check out once you know those dimensions. To determine the axle capacity you can do it a couple ways. There should be a plate or sticker near the tongue of the trailer that will have the overall trailer capacity as well as axle capacities. You...

  • On Trailer Brake Assemblies Which Brake Pad Faces Towards the Front of the Trailer
    On the Dexter brake assembly part # 23-27 that you referenced the small pad would face towards the front of the trailer. This is a "right hand" assembly which means it goes on the passenger side of the trailer. If you check out the picture I attached you can also use the arm the magnet is held on as a way to tell too. If you imagine it as the head of an arrow it should always point to the front of the trailer.

  • Troubleshooting a Dragging Electric Brake on a Trailer
    It sounds like there is an electrical short on your trailer wiring that is activating your left rear brake assembly and that is why the brake continues to drag and get hot. Since you have swapped the brake assembly out and still had the problem you know the problem is not in the assembly but somewhere else on the trailer wiring. I would start at the wiring near the brake assembly and check for corrosion and loose or exposed wires and fix as necessary. You will want to trace this back up...

  • Troubleshooting New Trailer Brakes Where One Side of Trailer Brakes Harder than the Other
    If the adjustment of both brake assemblies are good and you can notice that the one side of the brakes are pulling harder than the other that would lead me to believe that the problem is the grounds of the brake assemblies on the right side of the trailer. A lot of times trailer brakes ground to the frame. I would just run all of the grounds back to the main ground harness of the trailer to see if that fixes the problem. The other problem is that it could be that your brake magnets are...

  • Could Damaged Trailer Brake Magnets Cause Low Brake Output Voltage
    Definitely sounds like a bad trailer magnet due to wear that is causing your issues with low brake voltage. I attached a help article that covers how to troubleshoot them as well.

  • Troubleshooting Trailer Brakes That Pulse and Get Hub Hot
    Changing the output setting of your brake controller should not change how the brakes react when the pedal isn't pressed. The controller should be putting exactly zero volts on your trailer brakes without the pedal pressed regardless of gain setting. Did you watch the display of the controller when the trailer was pulsing? Did it show anything like an output setting moving with the pulsing? My theory is there's a mechanical problem on assembly that's getting hot that's causing them to grab...

  • Do Brake Magnets Need To Sit Perfectly Flat on Inside Armature Surface of Brake Drums
    In order for the trailer brake magnets to get full adhesion to the inside armature surface of the brake drum, the magnet face and the armature surface of the drum need to be perfectly flat and smooth. Since they aren't mating together perfectly, it's possible that this is could cause the braking problem you describe. You'll also want to make sure that the ground connection for each magnet is securely attached to clean, bare metal. Since it seems that you've eliminated everything else,...

  • Troubleshooting A Truck That Is Giving a Check Trailer Wiring Error
    There also is a pretty high probability that you have a bad ground. This should be attached to a clean unpainted surface that is free of rust. You'll also need to look to see if the connection is broken, loose, or damaged. If you check and it is not damaged and in an acceptable area, then I recommend try and trace your wires to see where the problem is. I have attached a FAQ that goes into a bit more detail on what you can do, and what to look for when you troubleshoot your 7-way.

  • Trailer Brake Controller Either Locks Up Trailer Brakes or Doesnt Brake Enough
    It is possible that the brake controller is mounted outside of the range specified in its manual and that could cause some unwanted behavior. If it is a time delay controller then you may need to adjust both the gain (power output) and the sync (how long it takes to ramp up to the preset gain level). You can also check to make sure both the trailer side and vehicle side connectors are clean and free of corrosion both on the pins as well as inside where the wires attach. I have included...

  • Selecting Trailer Wheels, Tires and Brakes for Off-Road Teardrop Trailer
    Vehicle wheels can have different offset than trailer wheels. Offset is any difference between a wheel's center line and the mounting surface. Positive offset moves the tire closer to the trailer frame and negative offset moves it away. This is why only special trailer wheels are recommended for use on a trailer. Similarly, only special trailer (ST) tires are recommended for use on trailers; passenger vehicle tires should not be used on a trailer, or vice versa. I linked for you our main...

  • Trailer Brakes Not Performing Well After Installing New Brake Assemblies and Drums
    The fact that a trailer brake won't lock doesn't necessarily indicate a problem. For best braking, you do not want the brakes to lock up. A skidding tire doesn't provide optimal braking. However, if you can get things adjusted so that the brakes apply to a degree just short of lock up, you'll have the most effective braking possible. Since you have new hubs and brake assemblies, you shouldn't need to sand anything. Since the magnets are getting 12 volts, the most likely cause of what...

  • Do Electric Trailer Brakes Work in Reverse
    Electric trailer brakes will work slightly in reverse but due to how the mechanism works they don't grab as hard in that direction. That's just the nature of the design. Sounds like yours are set up properly though. Good news is that you won't be travelling that quickly in reverse so the need for powerful trailer brakes in that direction isn't nearly as important as forward.

  • Are Electric Brake Assemblies Compatible with Boat Trailers?
    Yes. Electric brake assemblies like the Dexter 10 inch # 23-27 you referenced can be added to a boat trailer that will be submerged. Some boat trailer manufacturers are even getting on board with the electric brake idea due to cost and function. You will want to note the trailer connector does need to be disconnected before your trailer wheels hit water as electricity and water do not interact well. This will protect your vehicle and trailer from electrical surge issues. Then you simply...

  • Brakes on 2011 Komfort Resort Tandem Axle Trailer Not Engaging Properly
    I would begin by inspecting the magnets on the trailer brakes. If the magnets have windings or wear marks, the magnets are bad and will need to be replaced. You would need to match up your brake assembly size for the correct replacement magnet. The next thing you will want to check is the wiring to the brake assembly and the magnets. Make sure that the brake assembly has a good connection and that there are no cut or frayed wires. You will want to make sure the magnets are connected to...

  • Can 10 x 2-1/4 Inch Electric Trailer Brakes be Used in Place of 10 x 1-1/2 Inch Brakes
    You will need to measure the width of the inside of the drum where the pad makes contact with the drum to determine if you can go to the wider 10 x 2-1/4 inch assemblies. If you cannot then you would also need to change out the hub and drum. To do that I would need to know the inner and outer bearing numbers stamped into the metal of the bearings. If the hub is wide enough then you can use the 10 x 2-1/4 inch assemblies # 23-27 for the right side and # 23-26 for the left. It is also...

    If you are having issues with weak trailer brakes you will first need to start at the tow vehicle and test the trailer connector for voltage on the brake output wire. In order to do this properly you will need to turn the brake controller all the way up and apply the manual override. If you don't get a full 12 volts then you know the issue is on the vehicle. If the issues is on the vehicle then test the brake output wire directly behind the controller once severed. If you don't get 12 volts...
